****************************************************
* *
* descrizione: libreria di funzioni grafiche: *
* permette di gestire con facilita' *
* immagini, cornici, e veri e propri *
* pannelli colorati. *
* Il contesto di grafica va avviato *
* con FAB_grx_open() e alla fine *
* chiuso correttamente con la funz. *
* FAB_grx_close(). L'ambiente di *
* grafica e'impostato a 16bit per *
* default, comunque e' sempre *
* possibile scegliere la profondita' *
* di colori preferita tra 15/16/24/32*
* definendo semplicemente solo una *
* delle seguenti costanti all'inizio *
* del proprio programma che include *
* questa libreria grafica: *
* FAB_GRX_15 *
* FAB_GRX_16 (default) *
* FAB_GRX_24 *
* FAB_GRX_32 *
